1. Remove the spark plugs.
2. Lay the motor over, so that if there is anything in the cylinders they can run out.
3. Try to pull the rope to turn the motor. Can the rope be pulled now?
4. If you still can not pull the motor, try turning the prop. Is the motor in gear or in netural. If the motor is in netural, the prop should spin easily.
5. Put the motor in gear, and with the plugs still out of the motor, try to turn the prop and see if you can turn the motor over from the prop end.
6. If you can turn the motor at all, it is likely that the motor is not froze up, but you only have a recoil problem.
If you can't turn the motor at all, you may have a froze up motor, or you may have the recoil locking up the motor.
7. If, with the plugs out and with the motor in netural and if you still can't get the motor to turn, pull the cowel and take off the recoil mechanism.
With the recoil mechanism off try to turn the flywheel by hand. With the plugs out, the flywheel should spin easily, If it doesn't you have the motor locked up internally - likely caused by corrosion.
If so, tilt the motor forward, so that the spark plugs are facing up and fill each of the plugs with penetrating oil and let the motor sit for a week. As time goes by, try turning the flywheel. If it begans to turn a bit, just rotate it back and forth a bit, adding more penetrating oil as you go until you get the motor to spin freely.
8. If with the recoil off of the engine, you can have the motor spin freely with the plugs out and by turning the engine by hand, you have a recoil problem.
9. With the recoil mechanism off the engine, try pulling the recoil. If you still can't pull the rope, you have internal recoil problems which means that you have to disassemble the recoil mechansim and repair it as needed, you may have a frayed rope that is jamming the mechanism or a broken part that is jamming the mechanism. Repair as needed, and replace on engine, replace the spark plugs and you should be good to go.

Hello all.
I've been reading this thread with great interest as I have a Yammaha 2 stroke 5hp out board engine and I have the same problem with the starter cord.
I followed a lot of REW's above comments to try and sort my problem.
I am new to boating and every mistake seems like a big mistake in the beginning - but a quick learning curve!
My outboard was on the boat and wasn't run for about 3 months. I stupidity unattached the fuel hose and stopped the engine - not letting the fuel run dry in the engine and I heard this is a no no for outboards and may be why it froze up. When I came to pulling the cord it didn't move at all.
So I did a basic service and removed the flywheel at the top, then slowly moved/ rocked the prop shaft over two/ three days and got it turning Yay! Then I reattached the fly wheel and the cord pull well. So put it back on the boat and started it next high tide. Double yay!
I let it run for about 30 minutes in neutral and then put it in forward and reverse and checked all was well - it was - good as new.
Then the next day I tried to pull the cord again and it was stiffer/ tighter - but I could still put the cord and it started on the third pull.
I went away for a few days and thought I better run the engine when i got back and it was as stiff as a board. Right back to the starter cord not moving the fly wheel and not being able to move it by hand.
I tried REW's handy breakdown (above) and removed the flywheel and sparkplug , put it in neutral and couldn't turn the prop.
There was no liquids coming out the spark plug hole, im using the right mix of oil and petrol, there is oil in the gears by the propeller (I checked this on the first basic service I did) I grease gunned all the 'nipples' (still make me chuckle like a child) but what am I missing?
It's frozen up again but was running lovely three/ four days ago. Something needs some oil or grease but where? Am I missing something stupid basic? Should I put 'penetrating oil' in the sparkplug hole for a few days and take it from there? Can I do that with a 2 stroke engine?
Any of your thoughts would be greatly appreciated,
Thank you for taking the time to reading this post.
